Hi,
when I tried the last CVS version I got this:
$ perl Makefile.PL
Checking if your kit is complete...
Warning: the following files are missing in your kit:
t/data-20/text.xml
t/data-20/xml.po
Please inform the author.
Writing Makefile for po4a
So here's the report.

Erm, I prefer not to detail what exactly it looks for ;) Let's say that the
CVS version is "a bit broken". Let me commit what I have locally, and it
should do the trick.
Now it works as expected :)

And you got nothing, right?
po4a skips the generation of msgid containing an entity only (or tags only).
It will now issue a warning when such optimizations are done. Thanks for the
repport. [At least this is what I planned, but the msgid containing spaces
along with entities where not detected. This is also fixed]
Now it seems to skip this kind of msgids (the version I tried some days
ago didn't), but it has an irregular behavior. I've done the following
(meaningless) test:
...
<!ENTITY chap SYSTEM "chapter1.xml">
<!ENTITY chap2 SYSTEM "chapter2.xml">
<!ENTITY aaa "contens of aaa">
<!ENTITY bbb "contens of bbb">
<!ENTITY ccc "contens of ccc">
]>
<book>
&chap0;
&chap;
&chap2;
&aaa;
&chap3;
&bbb;
&chap;
&ccc;
&aaa;
</book>
and in the generated po, this part appears as:
# type: </chapter><chapter>
#: chapter2.xml:30
msgid "&aaa; &chap3; &bbb;"
msgstr ""
# type: </chapter></book>
msgid "&ccc; &aaa;"
msgstr ""
The type line is... pretty weird. It seems like it puts the last two tags
it has found. I don't know how it's treated, but i think it should be in a
stack-like manner, pushing the opening tags and poping the closing ones.
This could also be great to notify badly-structured documents. (I don't
know if it does currently)
A stack-per-file could be great, so that the messages in the included
files don't contain tags external to them.
In the example above I think the correct type would be <book>.
The reference line says it's from the included file, but it should say
it's in the main file instead.
When watching the contens of the msgids, it seems that it skips only the
inclusion entities that it knows, and gives the "substitution" entities
up:
&chap0;
-> &chap;
-> &chap2;
&aaa;
&chap3;
&bbb;
-> &chap;
&ccc;
&aaa;
and it treats the rest as 3 fragments alone. The first one (&chap0)
doesn't appear, because it's like a 1-entity message. The second and the
third appears.
I think there are 2 alternative ways to treat these cases better:
1) Exclude all entities-only messages (any number, known or unknown)
2) Include the whole messages that have more than 1 entity (known or
unknown), because in some languages it may be interesting to change
the order of some of them.
hmmm, now I was thinking about the standard entities that define special
characters, as ´ and I've seen that they're also excluded if there's
something like <title>&Acute;</title>. Seeing this, I prefer not to
exclude any entities. In some cases it can be a little annoying for the
translators, but else, there could be some untranslateable strings.
It was furthermore impossible to translate the content of the entity because
it was not implemented. This will be fixed as soon as I find the time to
commit my local version into the CVS. At least, I hope so ;)
Wow! Thanks, it's a great improvement :D I've only done small tests on
this, but it seems to work well ;)

If that's legal (ie, if nsgmls accepts it, I'll have to accept it. Again,
please fill a bug about this (another one). Do not forget to attach a
example file being valid, but refused by po4a. For example, are you sure
that it's %common; and not &common; ?
nsgmls accepts them, and it parses the included files (it has given some
errors in the included files ;)
The %something; entities are a different kind. I don't know all their
properties, but they're expandable into the doctype header (and standard
entities aren't). I'll fill the bug in a while.
